Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Deceleration Sensor (AWD Vehicles Only): Notes
The EBCM uses a deceleration sensor to sense vehicle motion.
The EBCM provides power (5 volts) and ground to the deceleration sensor. The deceleration sensor sends a voltage signal back to the EBCM relative to vehicle motion. This signal is about 2.4 to 2.6 volts at zero speed change (constant motion) and stationary, the voltage signal decreases when the vehicle is under acceleration, and the voltage signal increases when the vehicle is under deceleration.
The deceleration sensor is located under the LH front seat.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
